Mischmetall, an alloy of the light lanthanides, has been used in a variety of organicreactions, either as a coreductant in samarium(II)-mediated reactions (Barbier and Grignard-type reactions, pinacoliccouplingreactions) or as the promoter of Reformatsky-type reactions. It has been also employed as the starting material for easy syntheses of lanthanide trihalides, the reactivity of which has been
Clean and simple: Alkoxycarbonyl radicals generated from carbazates by iron catalysis in air underwent addition to a variety of alkenes to give the corresponding β‐hydroxyesters (see scheme). The simple experimental procedure for this transformation has the added advantage that the reagents are environmentally friendly. R1,R2=alkyl, alkynyl, aryl, CO2Et; [Fe(Pc)]=iron phthalocyanine.
